Compatible Jet Pumps 95 ZXI 750 or repair?

My pump froze on my 95 ZXI 750 and I was wondering if any other pumps would fit and what the differences are. The pump for the 1100 ZXI is more readily available and is cheaper too, but it has a different part number. They look the same but I haven't examined one closely enough to know if it will bolt on or work.

Any other suggestions for a locked jet pump? The corrosion between the housing and the wear ring bulged the ring and locked the impeller. Anyone tried to replace the wear ring?
